If you want to know the version, goto the settings option in the XBOX menu and select information. You will see lots of legal text. If there's no kernel version written you have a 3944.Else it's will be clearly written which kernel you have.

Hey guys new to this sorry for the noobness. I'm looking at getting the matrix chip but it only support up to 1.2. So how do i know if my xbox is a 1.2, 1.3,1.4,1.5? because the kernal only gives the range?thanks

hello XanTium thanks for your helpfull explanation about serial numbers and factorys but if my xbox is made after 2003 it doesn't help me very much. I bought a Crystal Limited Edition xbox (2004-02-06/612 2093905 40605) and plan to mod it with a chamelion and a 300 GB hd. Since the chamelion (the solderless bus that is) supports up to v 1.5 xboxes and rumor goes that the CLE xbox is a 1.6. I wonder how do I find out what version xbox I have?

My crystal's a v1.4 too. But if you're gonna open it up then you can check by looking behind the GPU (the one with the smaller shiny metal heatsink thing) and it should have a FOCUS video chip. That means it's either a 1.4 or 1.5, but there are no crystal 1.5s, so it is very likely to be a 1.4. If it says XLB ont he video chip, it's a 1.6, but only one person seems to have had this and it was in an australian crystal green xbox

Yes, your kernel version is 5713 ... which doesn't match any of the given kernel versions on this thread. So, that leaves us with the question of exactly what version this kernel refers to ... I am in the same boat

If I understand correctly I have a box with 1.2 - 1.5 Bios, and the only way to know for sure from here is to crack it open?Also I have two holes in CD tray with is a Samsung, and I understand that is a better one as far as reading CD-R's
